る。[Detailed description of the invention] (Field of industrial application) This invention is an improvement of a small high-pressure gas cylinder with a so-called safety seal plate, which allows gas to be discharged most safely and reliably when the gas pressure inside the cylinder rises abnormally. In particular, the purpose is to improve the strength of the safety sealing plate during normal times and to prevent natural leakage of gas due to rusting of the sealing plate due to moisture contained in the air.
（従来の技術）

険である。(Prior art) When the internal pressure rises abnormally due to a rise in ambient temperature, such as when an unused gas cylinder is dropped into a fire, the relatively thin sealing plate expands outward. After being released, the cylinder ruptures rapidly and explodes, causing the cylinder itself to fly in unspecified directions, making it extremely dangerous.

された。 Conventionally, in order to avoid the above-mentioned dangers, a local conical shape (a truncated conical shape) was formed in the center of the surface facing or behind the cylinder opening surface to be sealed, from one surface to the other. (including) a sealing plate with a recess
It was developed for use in small high-pressure gas cylinders of 100 c.c. or less, and was publicly announced as Utility Model Publication No. 56-34240.

を満たさない限り安全封板として十分に機能し得
ないことが実験の結果明らかになつている。(Problems to be solved with the invention) However, in reality, in the recessed part of the sealing plate mentioned above,
The relative dimension between the opening area of the recess and the wall thickness of the bottom is extremely strict, and is required as a safety sealing plate for small gas cylinders with a capacity of 100 c.c. or less in the event of an abnormal increase in internal pressure. The inner diameter of the concave part of the sealing plate required for gas leakage must be 0.8 mmφ or less, and the thickness of the sealing plate after subtracting the depth of the concave part (thickness of the concave part) must be 0.08 mm or less. Experiments have revealed that unless the requirements are met, the safety sealing plate cannot function satisfactorily.

がある。 Therefore, creating recesses in the sealing plate that meet these conditions not only requires extremely sophisticated technology and skill, but also requires the above-mentioned part to be created on the sealing plate, which is extremely thin compared to the gas cylinder body. The concave part is just an extremely thin wall part, and if this is used in a high-pressure cylinder, the extremely thin wall part corresponding to the concave part will inadvertently crack as a result of a slight increase in internal pressure, causing damage that will not occur over time. It is relatively common for all of the pressure gas to be released over time and the device will not function at all during actual use. Furthermore, since the material of the sealing plate is generally iron, if a small high-pressure gas cylinder equipped with the above-mentioned sealing plate is installed in a carbonated beverage manufacturing device or used for extruding draft beer, the content of gas in the atmosphere will be reduced. It is easily corroded by the influence of moisture, and even a small amount of corrosion often causes cracks to form locally in the extremely thin recesses of the sealing plate, resulting in gradual gas leakage or sudden gas leakage. There is a risk that it may open and pose a danger.

In the structure of the above-described embodiment, the recess 3 is normally completely covered with the filling/filling coating material to cut off contact with the high-pressure gas in the cylinder or the atmosphere, and at the same time, the thin wall inside the recess 3 is reinforced. This not only prevents accidental cracks from occurring due to slight increases in temperature and pressure, but also allows the sealing plate 2
is heated, as a result of which the filling/filling coating material in the recess 3 melts, allowing the recess 3 to fully perform its function as a safety seal.

口して危険をもたらすようなことが皆無となる。(Effects of the invention) As described above, the present invention forms a locally thinning recess on either the inner or outer surface of the sealing plate, and at the same time, the thermoplastic resin is formed inside the recess or on the entire side of the sealing plate including the recess. Since the filling material made of synthetic resin or low melting point metal is used to fill the recess, the inner surface of the recess does not come into contact with the high-pressure gas inside the cylinder or the outside air, thereby preventing corrosion of the locally thin walled portion of the recess. There is no possibility that the high-pressure gas in the cylinder will gradually be released without realizing it, or that it will crack and suddenly open, causing danger.

る。 At the same time, the thin wall inside the recess is reinforced, which not only prevents it from inadvertently cracking due to slight increases in temperature and pressure, but also prevents the above-mentioned filling or filling process from occurring due to the influence of ambient temperature in the event of an emergency such as a fire. The coating material dissolves easily and has various beneficial effects, such as not interfering with its original function as a safety sealing plate.
